Abstract

The invention relates to the technical field of transferring film, in particular to a scratch-resistant and folding-resistant transferring film, a production process, and application thereof. The scratch-resistant and folding-resistant transferring film comprises a PET base film and a transferring coating layer coating on the PET base film. Coating on the transferring coating layer is composed ofacrylate copolymer, polyester resin, polyurethane resin, polydimethylsiloxane, hydroxyethyl cellulose, polypropylene, ethanol, and water. The acrylate copolymer can improve the scratch-resistant performance of the transferring coating layer. The polyurethane resin can improve the tensile performance of the transferring coating layer, so as to improve the folding-resistant performance of the transferring coating layer. The synergistic effect of the acrylate copolymer and the polyurethane resin enables the transferring coating layer to have high film-forming performance and tensile performance.After the transferring film is attached to a wrapping paper by transferring glue, the PET base film is stripped off. The scratch-resistant and folding-resistant transferring coating layer does not have cracks during the bending process of the wrapping paper, and the wrapping paper cannot be exposed.

Description

technical field [0001] The invention relates to the technical field of transfer film, in particular to a scratch-resistant and fold-resistant transfer film, a production process and its application. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for product packaging. In order to improve and beautify the visual effect of packaging, transfer film is often compounded on the surface of packaging paper. The transfer film includes a PET base film and a coating. The PET base film is difficult to degrade naturally and will cause white pollution. As the country's environmental protection requirements are getting higher and higher, deplasticization of packaging paper is imminent. At present, the method of removing the PET base film on the surface of packaging paper is often used to meet the deplasticization requirements. However, since the PET base film has a bending-resistant effect on the surface of the wrapping p...
